Wow, this thread is getting waaaay cool! 8-) I know, I still owe several replies (and research) here... :I but for the time being I see very interesting the idea of a grayscale SE/30. With the video card issue already solved, this is what I think about the remaining tasks: The grayscale...

I'll be far from my Macs for a few days (and pretty busy!) thus I can't confirm this for sure, but I believe that even a stock SE/30 should be able to boot from CD-ROM provided that: The CD is bootable The System version is compatible with the SE/30 (up to 7.5.5) That system's configuration...

Hi and thanks (again) for the warm welcome... Things aren't that complicated, just more/new tasks at work with less pay :-/ but still can afford some hobbies anyway. Back to our thread, I've been experimenting a bit with the IIsi and the Radius Pivot PDS card... first of all, after this...

Phew! Hi again! Sorry for being absent all this time... life's got rather complicated and, among other things, I've been giving birth to my very-own-designed 6502 computer -- now that's retro! ;) Fortunately, things are starting to settle down now, so I'll be back into the delicious world of...

I overclocked my Quadra 700 with a socketed 64 MHz oscillator: The hard part was desoldering the ground pin... but otherwise it's a fairly easy procedure. I tried slower oscillators also, for the fun of it: down to 40 MHz is OK; 32 MHz starts having video issues... 24.576 MHz or lower, no...

AMAZING! We already knew it was possible, but seeing it actually running is just great 8-) If I understand it correctly, if no key is pressed upon power-up, the machine will try to boot from an ordinary disk, right? Could that be modified in order to make the Copy ROM to RAMdisk boot option...

Now that you mentioned the roadmap for CC upgrades... the 68LC040-based LC575 board is an easy upgrade, but why the change to a full 68040 is marked on red? Is it really "dangerous"? I expect it to increase heat dissipation, but fitting a small heatsink should suffice, am I wrong?

OK, let's go! (I'm writing this on the SE/30, after checking what you said) So does mine... These are exactly the values I read at $50F14806 if I change the volume setting via the usual control panel... Well, here we are a difeference: mine reads $02. FWIW, at $50F14801 is $01. Done ;-) I...

Phew... After a long time with tons of work, I'm back again ;) Glead to hear the discussion going on. I've had little time to keep twinkering on it, but here's an update/remainder of the state of my research: •The card supplies a 640x870 (portrait) signal, no matter the sense code applied...

[Wow! It's been a long time since my last post... I've been crazy at work these weeks :( I hope to catch up soon!] @onlyonemac: If memory serves, I tried every possible value for the register, including each combination of D0, D1 and D3 -- the volume did turn down making the sound...

2 & 8 MB SIMMs do not work on the SE/30 -- just 256K, 1, 4 & 16 M :( The IIsi (and I presume the IIci too) seems to take almost anything 30 pin, parity or not, composite or not, including 2 and 8 MB sizes. But the clearance issues aren't unique to the SE/30: the Quadra 700, for...

Oh dear... the MacMini is running 10.5.8 -- the system confuses the eight next to the ending ')' for a smiley xx(

Just downloaded, works great on: iMac 21.5" Core-i5, 8 GiB (OS X.7.5) MacMini Core2Duo, 2 GiB (OS X.5. 8) If needed, I can setup the last machine with the originally supplied version of Tiger, for further testing. Thanks again! PS: Any remarkable improvements in mind for the next batch of...

Strange... Please double-check all connections. You did remove the jumper previously used for firing up the PSU, right? Click here for the IIci's PSU pinout -- it's the same as the IIvx, Q800 etc. Also, make sure that the metallic enclosure of the transistor isn't touching any other contact --...

If I understand your idea correctly, that Universal PSU-Adapter PCB shouldn't be difficult at all... just take my previous schematic (for the IIsi) and connect the lines in parallel for each Mac-side connector. Some lines from the ATX PSU (e.g. the +3.3V rail, unused and thus not shown in the...

If I'm not mistaken, power dissipation should be around 1 mW -- won't generate any noticeable heat 8-) Good idea! I believe a PCB/Protoboard, no matter how small, would be overkill for such a simple circuit. Maybe this inverter could be installed inside the ATX PSU, alhough it no longer would...

Hi! Sorry for being so late to chime in -- very busy going back to work :'( Yup. It was here. It's a very sophisticated paperclip ;) but also the proof of concept that the ATX PSU can be soft-controlled by the IIsi... it's just a matter of placing an inverter between the /PFW line from the...

tt, your idea is quite feasible and interesting! The actual code for displaying a picture is about a 25% of the whole listing, just anything above the line: ;loop for trying every 0x802 value! and could be somewhat simpler with a bit of optimization -- this was a quick-and-dirty approach...

80-pin drives usually have no ID jumpers... ID is set via jumpers on the adapter itself. I believe there's no way to activate termination on a 80-pin drive, other than connecting an external terminator. Some high quality adapters include termination, though. I've been successful using large, 68...

While many Mac motherboards use a pretty similar form-factor, there are some differences... I have compared the 840AV to the 7600 board, and among other things, the power switch is differently located (left on the 7x00, right on the 8x0). I don't think a 7200 front part would fit the (awful) 800...
